Anyone running MySQL through a BigIP?

Hi, I'm trying to run MySQL traffic through a Big IP, but I'm having some issues. I'm load balancing four read databases and I'm getting "Communication link failure" messages in the client...

modify the TCP timeout settings for the TCP profile, but also ensure you are NOT using auto SNAT. specify a snat pool and modify the snat TCP timeout as well. That should fix it.

The issue we had with MySQL was with CMP and packet filters. The BigIP changed tmm for the traffic and blocked the traffic due to the return traffic was not allowed through the packet filter.
